From: | To: |
The Disabled Ramp Gradient Calculator determines the slope percentage and ratio of wheelchair ramps according to UK building regulations. It ensures accessibility compliance for people with mobility impairments.
The calculator uses the gradient formula:
Where:
Maximum Allowable Gradient: 1:12 ratio (8.33%) for disabled access ramps according to UK building regulations.
Details: Correct ramp gradients are essential for wheelchair users and people with mobility aids. Steeper gradients make ramps difficult or impossible to use safely, while proper gradients ensure accessibility and compliance with the Equality Act 2010.
Tips: Enter the vertical rise and horizontal run in meters. The calculator will determine the gradient percentage, ratio, and compliance status with UK building regulations.
Q1: What is the maximum gradient for disabled ramps in the UK?
A: The maximum gradient is 1:12 (8.33%) for ramps up to 10 meters in length. For longer ramps, shallower gradients may be required.
Q2: Are there different requirements for different ramp lengths?
A: Yes, ramps longer than 10 meters require resting platforms and may need shallower gradients. Always consult current building regulations.
Q3: What about ramp width requirements?
A: Minimum width should be 1200mm, with 1500mm recommended for two-way traffic and 1800mm for wheelchair turning.
Q4: Do I need handrails?
A: Handrails are required on both sides for ramps steeper than 1:20 (5%) or where the rise exceeds 600mm.
Q5: Are there exceptions for existing buildings?
A: While some flexibility exists for existing structures, new constructions must comply fully with current accessibility standards.
